I swear I intended to leave my thoughts on this much earlier, but life, studies and I guess procrastination gets in the way sometimes. Since I fully believe you could be Powergirl, please don't hurt me.
Anyway, let's get down to business. Holy shit, does this look impressive, not only for the bright, lively cityscape but for the actual flying pose as well. It's easy to believe that you built up some speed and took off with the force of a fighter jet. Guess in a matter of moments, you'll be airborne.
I couldn't begin to guess how you done this, but it doesn't matter, because overall, this is a technical masterpiece. The costume also adds some real spark to the flame. Superb work, Crystal, truly a showcase of your skills here.
